FIELD OF THE INVENTION

The invention relates to a new group of aromatic sulphonamides derivatives and their synthesis and use for modulation of the activity of protein disulfide isomerase (PDI). More particularly, the invention provides small molecule inhibitors of PDI A3 that display antiplatelet, antithrombotic and anticancer activities.

BACKGROUND OF THE INVENTION

Protein disulfide isomerase (PDI) is a thiol-oxidoreductase chaperone protein that is responsible for the isomerization, reduction, and oxidation of disulfide bonds. There are known over 20 members of the PDI family of enzymes. Structurally, prototypic PDI consists of four domains with a thioredoxin fold: a, b, b′ and a′, an extended C-terminus with KDEL ER retention sequence, and an interdomain linker x between the b′ and a′ domains. The a and a′ domains are catalytically active, contain redox active CGHC active site and independently can perform oxidation and reduction reactions (Darby and Creighton, 1995). The b and b′ domains are noncatalytic, but provide a substrate-binding domain of PDI. All four domains are needed to achieve the isomerization and chaperone activity of PDJ. Besides its catalytic role involving thiols and disulfides, PDI also serves an essential structural role as the beta subunit of prolyl-4-hydroxylase (Koivu et al., 1987) and as a microsomal triglyceride transfer protein (Wetterau et al., 1990).

Protein disulfide isomerase (PDI) catalyze posttranslational disulfide bond formation and exchange and serve as chaperones during protein folding (Hatahet et al., 2009). PDI has been also identified at many diverse subcellular locations outside the endoplasmic reticulum. It has biological functions on the cell surfaces of lymphocytes, hepatocytes, platelets, and endothelial cells (Manickam et al., 2008; Hotchkiss et al., 1998; Essex et al., 1999; Burgess et al., 2000; Bennett et al., 2000; Hotchkiss et al., 1998; Burgess et al., 2000). PDI is rapidly secreted from both endothelial cells and platelets during thrombus formation in vivo (Cho et al., 2008; Jasuja et al., 2010). Inhibition of PDI using neutralizing antibodies blocks thrombus formation in several thrombosis models (Bennett et al., 2000; Cho et al., 2008; Jasuja et al., 2010; Reinhardt et al. 2008). Inhibition of PDI in these models abrogates not only platelet accumulation at the injury site but also fibrin generation. Although number of studies focused on PDIA1, this isoform is not the sole isoform of PDI that support thrombosis in vivo and platelet aggregation in vitro. In particular, PDIA3 has an important role in the activation of the αIIbβ3 fibrinogen receptor and platelet aggregation that cannot be replaced by PDIA1 (Essex D W and Wu Yi 2018). Thus, deficiency of PDI A3 results in blunted platelet aggregation (Essex D W and Wu Yi 2018) due to the impaired activation of GpIIb/IIIa receptor that is a major platelet receptor for fibrinogen binding and is required for platelet aggregation and thrombus formation (Essex D W and Wu Yi 2018).

Importantly, PDI has been implicated in proliferation, survival and metastasis of several types of cancers (Lee et al, 2017, Xu et al., 2012; Hashida et al., 2011; Lovat et al., 2008) and the important role of PDIA3 was postulated (Yang Z et al., 2018; Hettinghouse A et al., 2018).

These observations demonstrate a critical role for PDIA3 in various pathologies (Cho et al., 2008) including thrombus formation and development of cancer. In particular, PDI A3 is a novel interesting target to develop antiplatelet, antithrombotic effects and anticancer therapeutics

Several patent documents provide compounds that inhibit enzyme activity of cell-associated protein disulfide isomerase e.g. US20160145209A1, WO2016118639, US20150133514A1, US20020115713A1, WO2017011890A1, but none of them relates to aromatic sulphonamides derivatives.

Presently, majority of available inhibitors of PDI are sulfhydryl-reactive compounds that bind covalently and are non-selective, acting broadly on thiol isomerases (Karala et al., 2010) or are cytotoxic (Lovat et al., 2008; Khan et al., 2011). Thus, there is a clear need for new agents that interfere with PDI A3 activity but are otherwise selective and well tolerated in therapeutic contexts. Now it has been found that some of among N,N-disubstituted aromatic sulphonamides possess unique pharmacological properties associated with their ability to inhibit PDIA3 activity, which property affords their antiplatelet, antithrombotic, and anticancer activities.

EXAMPLE 3. EVALUATION OF ANTI-AGGREGATORY EFFECT OF PDI A3 INHIBITORS IN VITRO AND THEIR ANTI-THROMBOTIC EFFECTS IN VIVO

Anti-platelet activity of compounds of invention was assessed using light transmission aggregometry assay of human platelet-rich plasma (PRP). Venous blood was obtained from male volunteers at the University Hospital Blood Bank Centre. Volunteer donors had not taken any medicines for the preceding two weeks. Blood was collected into vials containing sodium citrate (3.2%, 9:1 v/v) as an anti-coagulant agent. To obtain platelet rich plasma (PRP), blood was centrifuged at 260×g for 15 min. The platelet pure plasma fraction (used as a blank sample) was obtained by centrifugation of the remaining blood for 10 min at 2600×g. Aggregation of blood platelets was assessed in PRP with a dual channel Chronolog aggregometer (CHRONO-LOG) using a method previously described by Born³⁵. PRP (500 μl) was equilibrated for 2 min at 37° C. with a continuous stirring at 800 rpm and then stimulated with collagen to cause aggregation. At the beginning of each experiment, concentrations of collagen that induced sub-maximum aggregation response were determined. These concentrations were in the range of 1-5 mg/ml, respectively. All the tested compounds were added 2 min prior to stimulation of platelets with collagen. Transmittance was read 6 min after stimulation of platelets with an agonist. FIG. 1 present shows inhibition of aggregation of human platelets by reference PDI inhibitors; while FIG. 2, 3 show inhibition of aggregation of human platelets by PDI A3 inhibitors of the invention.

As shown on FIG. 1 , inhibition of platelet aggregation by reference PDI inhibitors in human PRP (Bepristat, LOC-14, CCF642 and rutin trihydrate) was tested. Data represent the means±SD of at least two independent experiments; n=2-8 replicates in each experiment.

FIG. 2 shows inhibition of platelet aggregation by 7 tested compounds among PDI A3 inhibitors according to invention. Experiments were performed in human PRP, data are shown in comparison to control; data represent the means±SD of at least two independent experiments; n=2-10 replicates in each experiment. The most promising compounds seem to be C-3390 and C-3399: as these two compounds have the lowest EC50 and their antiplatelet effects is shown on FIG. 3A. The other compounds have a lower potency, but all of them have a dose-dependent inhibitory effect on platelet aggregation in human platelet rich plasma as shown in FIGS. 3B and 3C.

As shown of FIG. 4 , there was a significant correlation between inhibiting PDI A3 (EC50) of selected PDI A3 inhibitors and theirs inhibitory effect on platelet aggregation (in 100 μM concentration). Experiments were performed in human PRP, data represent the means of at least two independent experiments; n=2-10 replicates in each experiment. These results support strongly the notion that inhibitory effects on platelet aggregation of compounds of invention is related to the inhibition of PDI A3.

To confirm antithrombotic activity of compounds of invention, inhibitors of PDIA3, pharmacological activity of selected compounds was tested in vivo in the rat or mice model of arterial thrombosis. Wistar rats were anaesthetized with pentobarbital (40 mg/kg, i.p.) and placed in a supine position on a heated (37° C.) operating table. Arterial thrombosis was induced by electrical stimulation of the right common carotid artery, as previously described (Kramkowski et al., 2012). Briefly, the anode, a stainless steel L-shaped wire, was inserted under the artery and connected to a constant current generator. The cathode was attached subcutaneously to the hind limb. The artery was stimulated (1 mA) for 10 min. Fifty-five minutes after the beginning of stimulation, the segment of the common carotid artery containing the formed thrombus was dissected and opened lengthwise, and the thrombus was completely removed and air-dried at room temperature for 24 h. Thrombus was then weighed in a blinded manner. Antithrombotic effects of compounds of invention in mice was analyzed using intravital fluorescence confocal microscopy as described previously (Hayashi T et al., 2008). GFP mice were anesthetized with pentobarbital (50 mg/kg, i.p.) a midline laparotomy incision was made, and then the mesentery of the ileum was pulled out of the abdomen and draped over a plastic mound. The mesentery was continuously perfused with 37° C.-warmed saline to prevent the vessels from drying. Mesenteric vessels were identified and endothelial injury was induced by a 514-nm argon-ion laser. For visualizing the surface-exposed platelet phospholipids in a thrombus, Alexa Fluor 568-labeled annexin V (ANX; 2-μg/g mouse body weight) was administered into the right femoral vein 14 minutes before laser injury. Changes in fluorescence intensity were measured as described previously (Hayashi T et al., 2008, Kramkowski et al., 2002)

FIG. 5 shows anti-thrombotic effects of C3990 and C-3343 two chosen compounds of invention in in vivo models of arterial thrombosis.

EXAMPLE 4. THE IN VITRO ANTIPROLIFERATIVE EFFECT OF PDI A3 INHIBITORS TOWARDS PANEL OF CANCER CELLS (48-HOUR EXPOSITION)

Anticancer activity of compounds of invention, PDI A3-inhibitors has been tested in vitro in classical antiproliferative assay in various cancer cells lines. Monolayer tumor cell lines MDA-MB-231 (human mammary breast adenocarcinoma), MCF-7 (human breast adenocarcinoma, estrogen-positive), HT-1080 (human fibrosarcoma) and Caco-2 (human colon adenocarcinoma) were cultured in standard medium DMEM (Dulbecco's modified Eagle's medium) (“Sigma”) supplemented with 10% foetal bovine serum (“Sigma”). About 2000-4000 cells per well (depending on line nature) were placed in 96-well plates and after 24 h compounds were added to the wells. Untreated cells were used as a control. The plates were incubated for 48 h, 37° C., 5% CO₂. The number of surviving cells was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolinium bromide (MTT). MTT-test: after incubating culture medium was removed and 200 μL fresh medium with 20 μL MTT (2 mg/mL in HBSS) was added in each well of the plate. After incubation (3 hr., 37° C., 5% CO₂), the medium with MTT was removed and 200 μL DMSO were added at once to each sample. The samples were tested at 540 nm on Thermo Scientific Multiskan EX microplate photometer. The half-maximal inhibitory concentration (IC₅₀) of each compound was calculated using Graph Pad Prism® 3.0.

EXAMPLE 5. ANTIPROLIFERATIVE EFFECT OF PDIA3-INHIBITORS IN VITRO IN HYPOXIC CONDITIONS AND IN CANCER CELLS STIMULATED WITH ESTROGEN

Anticancer activity of selected compounds of invention, PDI A3-inhibitors has been also tested in vitro in antiproliferative assay in normoxic and hypoxic conditions as well in estrogen-stimulated cancer cells. In the experiment, cells were seeded on 96-well plates (Sarstedt, Germany) in appropriate culture medium at a density of 10⁵ cells/mL 24 h before adding the tested compounds. Cells were treated with each compound in four concentrations in the range 0.1-100 μg/mL. Cisplatin (Ebewe, Austria) in the range 0.01-10 μg/mL was used as a reference drug. Dimethyl sulfoxide (DMSO), used as a stock solution solvent, was tested for antiproliferative activity and it did not affect cell proliferation at 0.1% (v/v)—a highest concentration used in compound solutions. After 72 h of compound treatment at 37° C., 5% CO₂ humid atmosphere and in wo different oxygen level conditions: 21%—normal and <1%—hypoxia. In some experiments the MDA-MB-231 and MCF-7 cells were seeded with or without 200 nM estradiol and after 24 h the tested compounds were added. A previously described sulforhodamine B antiproliferative assay was used with minor modifications (Skehan P et al., 1990). Briefly, cells were fixed with 50 μL/well of 50% (w/v) trichloroacetic acid (Avantor Performance Materials, Gliwice, Poland). After 1 h incubation, plates were washed several times with tap water and 50 μL of 0.4% (w/v) solution of sulforhodamine B (Sigma-Aldrich, Germany) in 1% (v/v) acetic acid (Avantor Performance Materials, Gliwice, Poland) was added to each well. After 30 min incubation at room temperature, unbound dye was washed out with 1% (v/v) acetic acid, whereas bound dye was solubilized with 10 mM unbuffered TRIS (Avantor Performance Materials, Gliwice, Poland) solution. The entire procedure was performed using a BioTek EL-406 washing station (BioTek Instruments, USA). After additional 30 min, absorbance was read using a Biotek Hybrid H4 reader (BioTek Instruments, USA) at 540 nm wavelength. MTT assay was used alternatively for HL-60 cell line and in the experiment in which estrogens are added (specified in the table legend). Absorbance was measured using a Biotek Hybrid H4 reader at 570 nm wavelength for MTT assay.

Compounds at each concentration were tested in triplicate in a single experiment and each experiment was repeated at least three times independently. Results of in vitro antiproliferative effects are shown in Table 3 and Table 4. Results are presented as mean IC₅₀±SD.

MTT assay was used for antiproliferative activity assessment.

In reference to Table 3 and Table 4, all new compounds tested in normal condition revealed antiproliferative activity comparable to LOC14. In reference to Table 3, the antiproliferative effect of C-3216 and reference inhibitors was comparable and normoxic and hypoxic conditions supporting the notion that antiproliferative effect of compounds of invention on human breast cancer cells MCF-7 and MDA-MB-231 is not dependent on oxygen access. Therefore, these compounds are effective in the hypoxic environment that occurs in the tumor. In reference to Table 4, it was established that the MDA-MB-231 line after treatment with estradiol (200 nM) shows slightly lower sensitivity to PDI A3 inhibitors: C-3375, C-3390, C-3399, a phenomenon that was not observed in MCF-7 breast cancer cell line.

EXAMPLE 6. EVALUATION OF EFFECTS OF PDI A3 INHIBITORS ON TRANSENDOTHELIAL CANCER CELLS MIGRATION IN VITRO

To assess whether compounds of invention, PDI A3-inhibitors are also effective as inhibitors of cancer cell transmigration through endothelium the transmigration assay with MDA-MB-231/lung microvascular endothelium was used as described previously (Stojak et al., 2018). Cell migration was assayed in 24-well, 6.5-mm internal-diameter Transwell plates (8.0 μm pore size; BD Pharmingen). Human lung microvascular endothelial cells (hLMVECs) were seeded into 24-well plates (seeding density 5×104 cells/insert) on the upper side of the filter and left to grow to confluence. After confluent monolayer formation, hLMVECs were pre-treated with 10 ng/mL IL-1β for 6 h. Prior to use in transmigration assay, cancer cells were pre-incubated with various concentrations (3, 10, 30, 50, 100 μM) of tested inhibitors of PDIA3, C-3390, C-3399 for 30 min. Then, MDA-MB-231 cells (each 5×104 per well) were placed into upper chambers and tested PDI inhibitors at various concentrations (1, 10, 30, 50, 100 μM) were given. Lower chambers were filled with medium containing chemoattractant (20% FBS or 100 ng/mL SDF-1α). After 24 h of co-culture, hLMVEC monolayers and non-migrating cancer cells on the upper surface of the membrane were removed. Migrated cancer cells on the undersides of the Transwell membranes were detached and stained by Calcein-AM-Accutase solution for 60 minutes. The cell number was determined by measuring the fluorescence using plate reader. Experiments were performed in triplicates and repeated three times.

In reference to FIG. 6 a , compound of invention C-3390 inhibited MDA-MB-231 cell transmigration across IL-1β 10 ng/mL (6 hours)—stimulated hLMVECs, in a concentration-dependent manner The number of migrating MDA-MB-231 cells through the hLMVEC monolayer was quantified by measuring the fluorescence, as described in Methodology. Data represent mean±SD of three independent experiments. Statistical analysis was performed using one-way ANOVA. Symbols mark the statistical significance levels as follows: (*) indicates p<0.05 as compared to IL-1β 10 ng/mL-stimulated group

In reference to FIG. 6 b , compound of invention C-3399 inhibited MDA-MB-231 cell transmigration across IL-1β 10 ng/mL (6 hours)-stimulated hLMVECs, in a concentration-dependent manner. The number of migrating MDA-MB-231 cells through the hLMVEC monolayer was quantified by measuring the fluorescence, as described in Methodology. Data represent mean±SD of three independent experiments. Statistical analysis was performed using one-way ANOVA. Symbols mark the statistical significance levels as follows: (*) indicates p<0.05 as compared to IL-1β 10 ng/mL-stimulated group

Therefore, tested compounds inhibitors of PDIA3 inhibited transmigration of breast cancer cells across hLMVEC monolayer in a concentration-dependent manner.
